I use Scheme/Haskell for most of my scripting purposes, the only exceptions being the cases where I want to make use of some extant library, in which case I switch to Python/Ruby. I used stumpwm for a while, which was written in Common Lisp, and a few months ago switched to XMonad, which is all Haskell. All my editing is done in Emacs, which uses a variety of Lisp (elisp.)

Given that close to 100% of my time is spent in XMonad, and >50% of my time is spent in Emacs, and every session involves at least some interaction with my collection of scripts... I'd say I use quite a lot of useful programs written in those fanfare-laden languages.
